We have just added some information about the Subaru 6 speed racing gearboxes available from Elite Racing Transmissions.

There are now 2 versions of the Subaru transmission, both are 6 speed sequential.

The smaller 4XL250 6s is based on the early 5 Speed box.
The New 4XL350 6s is based on the 6 speed box.
The limiting factor on the smaller Subaru transmission is the crown wheel and pinion size.

Where the larger box runs a bigger crown wheel and pinion and is stronger.

Both transmissions run the same gear set.The smaller 4XL250 6s is rated at up to 450ftlbs tourqe.

You need a donor 5 speed center diff and this box uses the standard 5 speed drive shafts and prop.

The larger 4XL350 6s is based on the 6 speed box, so uses the standard 6 speed center diff, shafts and prop. This is rated to around 700ftlbs!.

Both Subaru transmissions use a 3.9 final drive at the front, and the drop
gears can compensate for a 4.1 or 4.4 at the rear.We can provide the sequential lever and mount. then you make a rod with
rose joint at either end, or run a push pull cable.
Or you can couple it up to your current gear lever.

The way these transmissions are built is to send a center diff to the factory in England, and they fit it all during assembly & test it.

Or If it’s cheaper, Elite can source a center diff in Europe and send it to you complete, to save the freight sending a Diff it around the world.

Both transmissions come with a front plated LSD and you can choose your own ramp angles!
